Greed is Good!

Two stockbrokers, Mr. Greed and Mr. Avarice, hold stocks of Company Gordon and Company Gekko respectively. Both stockbrokers sell their respective stocks of Company Gordon and Company Gekko for $1000 each. Stockbroker Mr. Greed calculates his profit based on cost price while Stockbroker Mr. Avarice calculates his profit based on selling price. While both claim to their clients to have made 25% profit, who is really hoodwinking his client and who has actually made more money for his client?
